Referring to the drawings: A designates the bed plate of a sewing machine, B the gooseneck or overhanging erm; C the needle arme;

D the needle bar and E the needle, said parts being of any usual and well known construe`A tion.

.Longitudinally movable in ways F on the bed A, is theslidng plate G, andi ways or i guIdesI-I on said piat'@G,nnd ai, ri htangles .':lothe waysF, sliding plate K ving sea 'cured thereto, at er near one end 'ihereo a plate L which is provided with a Standard To said standard is pivoted or hinged aplate N, to which is secured the button holder P,

said holder consisting of two spring arms connected to the blocks Q whichare movable either toward or from each other on 'the plate N by'xneans of the 'right and left.; threaded screw R, working in said blocks,.\ andV 'sw-iv- -eled in a standard S on saidplate N. Each of the said blocks is` providedl oIIits-under face with a rib, which fits in a slot U in the plate N, so that the said blocks will move in a right-line. The outer-,ends of the holder P `are curved or indented to reliably hold a lout-4 ton between them, so that thesame 'me-ayube sewed on the article desired.-

-To operate the sliding plates G and K the following mechanism. is employedi Mounted on the driving shaft V of the machine, and below the bed plate A', is a grooved cam switch W, in the grooves of which projects a stud X on the lever Y, which .latter is pivoted at one of its ends to the bed plate A. The lever Y has a link Z connected with a lever A which is pivotally secured. at .its end, opposite from that of the lever Y, to the bed A, said link having its ends provided with studs which are adjustable in slots B and,V Gfrespecti'vely in said levers Y and A. Secured to the lever A between its pivoted end and the link Z, by means of a block movable in a slot in said lever is a sliding plate D, which is fitted in the' guides E on the bed A, and has an arm F mounted on a standard G thereon, the

said block also movingin a slot in the said plate. One end of the said arm F has on its upper face a studG adapted to eng-age in a slot H in one limb of an elbow lever Jplv -oted to the bed A, and having its other limb with a'bifurcated end embracing a stud K on the slide K, whereby the oscillation of said .elbow'lever imparts reciprocating motion to said slide K, On the under face of the same end of the arm' F', as the stud GX, is a stud'L' adaptedv to engage ina slot oropening M. in

the plate G, so thatthe` reciprocating movement fof saidarm F may impart 4a reciprocating movement to said plate G. On a ver tical stud N on the plate D'is a rotary ratchet wheel P', and also mounted on the same stud, is an arm Q carrying a spring -controlled 2 nearer pawl R. The said arm Q' is connected with the lever Y by means of a link S', said link b'eing adjustabiy connected therewith by means of a stud or pin T', which is secured in a slot U' insaid lever. A. cam plate V' is secured to the upper face of the ratchet wheel P', so that during the rotation of said ratchet wheel, the adjacent end of the arm F' which is provided kwith a roller X', riding on said ratchet wheel and cam, may be raised so as to depress at the proper time the other end of the said arm, and thereby secure the stud L' in the opening M'and thereby the said arm to the plate G. A spring Y' secured to thebed plate A, and bearingagainst the end ot' the arm F' having the studs GX and L' thereon, forces the said end upward when the roller X' is riding on the ratchet wheel, so that the stud GX enters the opening H of the elbow lever J and thereby connects the arm F' with the slide K, leaving the slide G free from the said arm. The shaftV-is operated by means ot' the driv" ing wheel Zwhich isloosely mounted thereon, and has its rim adapted to bear against a leather or other suitable gasket between it and the surrounding rim of the wheel A2 rigidly secured on the said shaft, so that when desired the two wheels -Z' and A2 may be clutched. Mounted inthe hangers B2of the table A is a bar C2 having one end secured to an arm D2, which at lone end is connected with the wheel Z', so that while permitting its free rotation itis adapted to force it into contact with the wheel A2. Bearing against the other end ofthe bar Ulis one limb of an elbow lever or latch DX pivoted to a suitable depending attachment of the bed A, the other limb projecting through a slot E2 in the said bed and adapted to fit in a recess F2 in the side of said slot, when the wheel Z' is clutched With the Wheel A2. Onthe plate D'is pivoted an elbow lever G2, one limb of which is adapted to be engaged by a pin 112 on the ratchet Wheel P', and the other limb to bear against the upwardly projecting limb of the lever DX and release the same from the recess F2, thus permitting the spring J2on the bar C2 between the collar K2 on the said bar and a hanger B2 tosc move the said bar as to release the piece D2 from bearing against the wheel Z',and at the same time bring a shoe L2 on the said piece D2 against the outer face ot" the wheel A2, thereby locking the latter in place. Hetween and bearing against a collar M2 se cured to the bar G2 and the lever DX is a coiled spring N2, forming a'springcounection for the said lever and bar. To raise the button holder 1, so as to be able to remove Vthe work from beneath the saine, the plate N, which is pivoted to the standardM of the plate L,'is provided with a lever P2, which is mounted in a standard Q2 on said plate N, and adapted to bear against the standard M as a fulcruin, whereby the plate N may be raised, thus lifting the holder l2 from the work. A. stud R2 secured to the plate L and freely passing through an opening in the piatte N, has on its upper threaded end a' nut S2, between which and the plate N, a coil spring SX is located, the latter normally serving to keep said plate lowered, so that the button holder attached thereto will rest on the Werl: placed on the bed A.

:Ihe manner of, Operating the machine is as follows: The button to be served on is placed in the holder over the needle opening in the plate K, so that the diagonal holes in said button are in line with the direction of the movement of the plates G and K. The driving wheel Z is operated to connect iv-ith the shaft V, so as to rotate the latter, by pulling down on the lever D by means of the chain T2 depending from one limb thereof. This movement of the lever locks its upper limb in the recess .F2 and forces the bar C2 so that the arm D2 bearing against the wheel Z' clutches it with the wheel A2, and at the same time releases the shoe L2from the outer face of the wheel A2, so that the latteris free to rotate. ,Owing -to the rotation of the shaft VLwith the cam switch lV, the lever Y is oscillated thereby imparting reciprocating motion by means ot' the link Z to the lever A and thereby tothe sliding plate D'. By moans of theilink connection of the arm Q' with the lever Y, and the rotary motion of the ratchet wheel 'P' with the cam plate V' thereon, con-- neotion is either made by the arm F' with the plate G by the stud L', orA with the plate' K by the stud GX and the elbow lever-J, so that the said plates are moved,as desired and cross stitches made, securing the button to the cloth. The number oi. stitches made in one direction before a sliding plate is disengaged from its operating mechanism and the other plate is engaged thereby, is regulated by the connection of the link S with the lever Y. The nearer the end ot' the lever said link is secured, the greater the throw ot the arm Q and the pawl R', and the faster the rotation oflthe ratchetwhecl P' with the cam plate V' thereon, thus lesseuing the time of travel of the roller X'fon the upper face of the ratchet wheel, and thereby the connection of the arm F' with the elbow lever J' and the plate K. W hen the roller travels on the canrplate V', the arm F'is released from the elbow lever J', and the plate G is engaged, whereby stitches are made crosswise to those sowed whilethe plate K was operated. lVhen the ratchet wheel l" rotates so as to bring Elo` the pin 112 against th-o lever G2, the latter trips or releases the lever DX from the recess F2, thereby permitting the spring J2 to operate the bar C2 so as to free the wheel Z' from the wheel A2, and at the same time clamp said wheel A2 in fixed position by brake L2, thus stopping the rotation ot theshattA in time to hold the needle clearot' the worlc'. As the holes or openingsare at different distances apart in different buttons, the play or travel of the slides G and l regulated by the conu nection of the link Zwith the levers Y and ft', said connections being adjustable by tgo 'means' of:4 the 'fastening pinsjon 'the endsjot thelink 'beingmovable in the slotsB' 'and'C, as Vbefore -stated, :when theclamping nuts thereof areloosened.
